研究的合著者Laura Lewis解释道:“我们早就知道神经元里有这些活动电波,但此前我们并不知道脑脊液中也有波。”
The new study — the results of which appear in the journal Science — included 13 participants ages 23–33 who agreed to undergo brain scans while asleep.
这项新研究的结果发表在了《Science》期刊上,研究对象是13个23-33岁的人,他们同意在睡眠期间接受脑部扫描。
They saw that cerebrospinal fluid appears to "synchronize" with brainwaves, which likely helps remove brain waste. This waste includes potentially toxic proteins that may otherwise form buildups that can impair the flow of information between neurons.
他们看到脑脊液似乎与脑电波“同步”,可能有助于清理大脑垃圾,包括潜在的有毒蛋白质,它们可能会在神经元之间形成阻碍信息流动的结构。
These findings, the researchers add, could also shed fresh light on the underlying mechanisms in conditions such as Alzheimer's disease, in which toxic protein plaques play a key role in memory loss and other cognitive impairments.
研究人员补充说这些研究结果也揭示了阿尔茨海默症等疾病的潜在机制,主要是有毒蛋白斑块导致记忆丧失和其他认知障碍。
They also explain that normal aging may be associated with poorer self-cleaning in the brain. With age, human brains tend to generate fewer slow waves, which may reduce blood flow in the brain, as well as cerebrospinal fluid pulsations.
